centos7搭建本地yum源

1、創建掛載目錄

#]mkdir /mnt/cdiso

2、將鏡像掛載到創建的目錄中

#]mount -o loop /home/CentOS-7-x86_64-Everything-1804.iso /mnt/cdiso

3、刪除yum源路徑，並創建新的

#]mv yum.repos.d/ yum.repos.d.bak
#]mkdir yum.repos.d

4、在/etc/yum.repos.d/下創建新的.repo文件，編輯後保存退出:

 [root@v-ct-jy-gkzhgg-web-01-0002 zabbix-3.4.2]# vim /etc/yum.repos.d/CentOS-local.repo 
[base-local]  #倉庫的id
name=CentOS7.2-local #倉庫的名字
baseurl=file:///mnt/cdiso  #iso掛載的地址
enabled=1  #是否開啓yum源  1-啓用 0-不啓用
gpgcheck=1  #安全檢測  1-啓用 0-不啓用
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

5、清除舊的yum緩存信息

[root@gkzhggdb01 yum.repos.d]# yum clean all

6、並創建新的yum緩存：

[root@gkzhggdb01 yum.repos.d]# yum makecache

7、查看安裝的yum倉庫

[root@gkzhggdb01 yum.repos.d]# yum repolist

base-loca                                      CentOS7.2-local                                  3,855
repolist: 3,855

至此，yum源創建成功
